portrayal.dev
Pick devices to read what the library states about them side by side. Every cell says where its figure comes from: derived is counted or measured off the drawing or the chassis, stated is read from the model. A figure nobody has put in the model reads not modelled; that is not zero, and it is not a statement that the device lacks it.
No device chosen yet. Add two or more, or start from an Edgecore switch and a desktop box.
Read off each device's chassis and its default front and rear drawings. Ports are counted per drawn port element, by media and speed.
The model's own sections, keys sorted within each. Values are the vendor's words with their units, so nothing is added up or divided here, and two keys line up only when their names are the same.
